Properties of Materials

Properties of Materials

By Tammy Rumplik

​

A characteristic or trait of matter that​ can be described by observation or measurement.

​

​Some text here about the topic of discussion.

​What is a property?

​

​The ability to bend or move easily without breaking.

What is flexibility?

​The ability of a material to have its shape changed (drawn out into wire or thread) without losing strength or breaking.

What is ductility?​

​

​​A measure of how hard something is. They can resist pressure and can be hard to cut, shape, or scratch.

What is hardness?

​Heat conduction or thermal conduction is the movement of heat from one object to another when they are touching each other.

​

​What is thermal conductivity?

​

A certain temperature at which a substance changes from a solid to a liquid. Every solid has its own melting point.​

​

​What is melting point?

​

Ceramics are usually hard but break easily. They have a high melting point and they do not corrode. They are good insulators because they don't conduct heat or electricity.​

​

​Ceramics properties

​

It is strong and stiff. It has different properties in different directions. Different types of wood have unique properties. Wood can not melt.​

​

​It is easier to chop wood in one directions as hardness of the wood can change.

​Wood Properties

​

Metals can be shaped and conduct heat and electricity. Metals can be combined together which form alloys that are stronger and harder.​

​

​Steel is an example of an alloy.

​Metal Properties

​

Plastics are made of long chains of molecules called polymers. Plastics can be heated and shaped. They are strong, are not conductors, and do not corrode.​

​

​Common plastic melts at 100 degrees Celsius or (212 degrees Fahrenheit).

​Plastic Properties

​

​Are materials that ​do not move thermal (heat) energy or electrical energy through them well.

​

Insulators

​Are materials that move thermal and electrical energy through them easily.​
